This is a divided possible corningware or glasbake company vintage casserole dish.No markings other than a 5 on one handle,and the corn flower or federal flower design on sides.I normally deal in vintage pyrex but this is still in that category.1 1/2 qt.,12 inch full length,10x8 usable cooking area.The outside is in very good to excellent condition.The inside is a little scratched in one spot,perhaps a knife or sharp utensil was used once.See picture #3.Other than that its just light normal ware for the age,Still very clean and in usable condition.The bottom is a textured dot pattern with minor scratch,again normal use marks cant photograph it.I pride myself on accuracy in descriptions,Please remember the item is old there are imperfections I try to disclose to the best of my ability.Thanks for looking.
